X-Men: Days of Future Past2014

[Charles reads Logan's mind and appears in the future where Professor X awaits him.]

Professor X:
Charles.

Charles Xavier:
Charles.

[Charles looks around to see the dire situation that both mutants and humanity face with the Sentinels in 2023.]

Charles Xavier:
Is this what becomes of us? Erik was right. Humanity does this to us.

Professor X:
Not if we show them a better path.

Charles Xavier:
You still believe?

Professor X:
Just because someone stumbles and loses their way, doesn't mean they're lost forever. Sometimes, we all need a little help.

Charles Xavier:
I'm not the man I was.

Professor X:
You're afraid. I remember.

Charles Xavier:
All those voices... so much PAIN.

Professor X:
It's not their pain you're afraid of. It's yours, Charles. And as frightening as it can be, that pain will make you stronger. If you allow yourself to feel it, embrace it, it will make you more powerful than you ever imagined. It's the greatest gift we have: to bear their pain without breaking. And it comes from the most human part of us: hope. [He shows Charles his school for Mutants, which helps ease his past self's mind.] Charles, we need you to hope again.
